I am the managing director of Coulson Legal, a specialist law practice offering services nationally in relation to legal costs between solicitor and client, and party and party.
I was admitted as a barrister and solicitor of the Supreme Court of WA and of the High Court of Australia in 1995. From 1995 to 2003, I practiced as a barrister and solicitor, predominantly in commercial litigation. From 2003 to 2011 I practiced almost exclusively in the area of legal costs from the independent bar, as Head of Chambers at Sir Ronald Wilson Chambers. In 2011, I established Coulson Legal. Since 2003, I have been an accredited Grade 3 Arbitrator with the Institute of Arbitrators and Mediators Australia, and in 2011, was appointed to the Law Society of WA’s Panel of Mediators and Arbitrators as an Arbitrator.
I have practiced almost exclusively in the area of legal costs since 2003, and have advised on and acted in hundreds of party/party and solicitor/client costs disputes in Western Australia, advising on and appearing as counsel in Western Australia on numerous contested costs applications, such as special costs applications, lump sum costs applications, applications for enlargements of time, and security for costs applications. I have also advised on and acted in a number of costs matters in Victoria, Queensland and NSW. Promoting ADR mechanisms is a priority for me, and I have avoided the taxation process for countless costs disputes by utilising ADR, including acting as a neutral evaluator in expert costs determinations.
In my capacity as a member of the Law Society of WA's Costs Committee, I have regularly provided input into legislative changes and revisions of scales of costs in WA. I have also had various papers published regarding legal costs, and I have presented numerous seminars to the legal profession regarding costs issues in WA.
When not considering legal costs, I enjoy zumba, water sports, boating, and photography.
